Building A Santa Cruz, CA 95060 Prepared by: Ebbin, Moser + Skaggs LLP Hagar Environmental Science Dana Bland & Associates Entomological Consulting Services, Ltd. Kittleson Environmental Consulting Services Biotic Resources Group DRAFT Administrative Draft City of Santa Cruz O&M HCP Executive Summary The City of Santa Cruz (City or Applicant) has applied for an incidental take permit (ITP) from the U.S. Fish and Wildlife Service (Service) pursuant to section 10(a)(1)(B) of the Endangered Species Act of 1973 (ESA) as amended (16 U.S.C. 1531 et seq.) to incidentally take the federally endangered Ohlone tiger beetle (Cicindela ohlone); the federally endangered Mount Hermon June beetle (Polyphylla barbata); the federally endangered tidewater goby (Eucyclogobius newberryi); the Pacific lamprey (Lampetra tridentata)(a species not currently listed under the ESA); the federally threatened California red-legged frog (Rana draytonii); and the western pond turtle (Actinemys marmorata), a federal species of concern. Additionally, the City is proposing to include four plant species in the Habitat Conservation Plan (HCP or Plan) and permit because of the benefits provided to such species as a result of the Plan’s conservation strategy and to receive the “No Surprises” regulatory assurances. The four plant species are the federally endangered Ben Lomond spineflower (Chorizanthe pungens var. hartwegiana); the federally endangered Robust spineflower (Chorizanthe robusta var. robusta); the federally threatened Santa Cruz tarplant (Holocarpha macradenia); and the State endangered San Francisco popcornflower (Plagiobothrys diffuses). The Plan refers to the plant and wildlife species proposed for coverage under the plan as Covered Species. Any reference in this Plan to incidental take of Covered Species under the Plan shall, for the purpose of covered plant species, refer to loss or impacts to covered plant species identified in the Permit. The potential taking of the covered wildlife species would occur as a result of activities permitted under the ITP (Covered Activities) and described in the Plan and include operation, maintenance and rehabilitation of the City’s water supply and water system facilities; operation and maintenance of the City’s municipal facilities; and management of City lands. The area covered by the HCP (Plan Area) is located in Santa Cruz County on the Central Coast of California, approximately 70 miles south of San Francisco. The total watershed and water service/urban areas comprising the general Plan Area are approximately 176 square miles and include three geographically distinct areas: the North Coast watersheds, the San Lorenzo River watershed, and the Santa Cruz urban center. The Plan discusses in detail the impacts to Covered Species and their habitats that are expected as a result of Covered Activities. As a result of these anticipated impacts, the Applicant has applied for a section 10(a)(1)(B) incidental take permit and proposes to implement the HCP as described herein, which provides measures for minimizing and mitigating adverse effects on the Covered Species. The Applicant requests that the permit be issued for a period of 30 years. The HCP summarizes the Covered Activities and identifies the responsibilities of the City and the role of the Service under the Plan. The HCP describes measures that will be implemented by the Applicant to minimize and mitigate impacts of the project on the Covered Species and their habitats and to further the conservation of these species. The conservation strategy in the Plan includes measures to mitigate impacts to Covered Species and their habitats that are not avoided Administrative Draft - i - through minimization measures. The City commits to fully fund the Plan and the Plan includes descriptions of costs for implementing the Plan and sources of funding to cover those costs.
